The Enugu State Electricity Regulatory Commission (EERC) has ordered MainPower Electricity Distribution Company to refund over 20,000 customers who were overbilled for electricity consumed in April 2025.
The directive, issued on Monday by EERC Chairman, Chijioke Okonkwo, and Commissioner for Market Operations, Reuben Okoye, followed a detailed investigation into the company’s billing practices, which revealed widespread violations of estimated billing regulations.
“The commission has issued an Order to MainPower to refund the affected customers the overbilled units for energy consumed in April 2025,” the commission stated, noting that the full list of affected customers has been published on its website.
MainPower has until the July 2025 billing cycle to complete the refunds. Failure to comply will attract a penalty of ₦500,000 for each day of default, in line with the Enugu State Electricity Law 2023.
EERC disclosed that it had been monitoring MainPower’s billing methods since October 2024 and had issued multiple warnings. However, the company allegedly failed to implement corrective measures, prompting regulatory action.
According to the commission, MainPower’s violations of billing caps worsened significantly, with estimated billing discrepancies increasing from 24% in February and March 2025 to 34% in April 2025.
EERC urged affected customers who do not receive refunds by the July deadline to lodge complaints via email at info@eerc.en.gov.ng or call 09122642755 for resolution.
The regulatory body reaffirmed its commitment to consumer protection and transparency in power distribution across Enugu State.
